I am a radiologist, i loved this video and i think you are the best anatomy teacher of the internet. I wish you did this same video but with a bone reconstruction CT scan. The one you are using is a soft tissue reconstruction, useful for assessing the brain in this case but the price you pay is very low quality imaging of the bone. With bone reconstruction CT for the sinuses you can see every individual air cell of the ethmoid and how they connect with each other, every foramina, every little suture! You would love it. Check out the radiopedia article about paranasal sinuses and look at the case examples with bone reconstruction I wish you someday do CT / MR anatomy videos, or even a course! You would show peaople another prespective that is very useful for understanding 3D anatomy, and you be a blessing for all the radiologists. I encourage you to try and do it, and see how radiologists all over the globe become your fans!! Much of us would greatly benefit from the deep understanding of anatomy you provide.
Are you kidding me?! You shining the light through the bone just showed me that I'm not insane. I recently suffered a cerebrospinal fluid leak which caused intercranial hypotension and we are now in the beginning stages of trying to find the leaks location and whether it's cranial or spinal. Seeing just how sheer the facial bones are blew my mind. I'm having rhinorrhea (post nasal drip right at the back of the throat) which could also be linked. I'm just now worrying about just how delicate these bones are and how nuanced it must be to try to find leaks location/fissure with imaging. Thank you for this video, very insightful. Wish me luck trying to find my leak!
@@edwardturitwenka6115 We came to the conclusion that it's autonomic rhinorrea caused by low csf pressure from a spinal csf leak. The low pressure makes the brain sag downwards, its increased weight then puts pressure on the cranial nerves and can cause lots of strange symptoms. It is just a coincidence that both cranial and spinal csf leaks can cause a clear fluid to run from the nose. I had the fluid tested and it was negative for Beta 2 transferrin so it wasn't CSF.
thank you so much it's so useful and it's clearer now ! can you please talk about other anatomic structures on cerebral CT scan and also MRI ?? you made me love and understand anatomy and it helps a lot in understanding pathology and symptoms , thank you so much !!!!!!
@samwebster You did an amazing job, breaking these down. Question that I would have loved to ask if I was sitting in your class... as far as the sphenoid and ethmoidal cavities, where would a ballon sinuplasty would be most likely to be done? Also, it would be helpful to see how they all connect to each other. Or do they?
Good job But not much information Dr.) CT is a great modality to show ostium of sinuses, osteomeatal complex and other things you can't visualisate in models
Hello greetings question: 1) What could be the possible diagnosis for the symptom of a foul odor emanating from one of the nasal openings "nostrils" considering the findings of a CT scan ? 2) Could the presence of mild mucosal thickening in the CT scan, potentially explain the occurrence of a bad odor originating from one of the nasal passages? please ignore if one the questions if not apply of what you see on the CT scan result . in advance thank you IMPRESSION: 1. Mild bilateral maxillary sinus mucosal thickening. No opacification or air-fluid level. Findings are similar to the prior CT from 11/29/2022. Signed by: mmmmmm MD 8/28/2023 Narrativa CT FACIAL SINUSES WO CONTRAST 8/28/2023 11:13 AM AGE: 47 years GENDER: Male HISTORY: Unspecified disturbances of smell and taste COMPARISON: 11/29/2022 CT facial sinuses TECHNIQUE: Helically acquired CT of the facial bones without contrast. Axial, coronal and sagittal reformatted images were produced and interpreted. DOSAGE: Total exam DLP: 298 mGy-cm. CTDIvol (max): 24.8 mGy. Number of acquisitions at maximum CTDIvol: 1. Dose reduction was performed with automated exposure control, iterative reconstruction technique and/or adjustment of the mA and/or kV for patient size. TIMING OF STUDY WITHIN 24 HOURS OF ARRIVAL IN HOSPITAL: As outpatient FINDINGS: Metal plates and screws lining the anterior bilateral maxillary bone appears similar and uncomplicated. Old healed fracture deformities of the maxillary bone and the right and left lamina papyracea. No acute fracture identified. No findings to suggest lytic or blastic bony lesion. Soft tissue: Normal. The TMJ joints appear unremarkable. Sinuses: Minimal right frontal mucosal thickening. Mild bilateral maxillary sinus mucosal thickening. No opacification or air-fluid level. Mastoid air cells: Clear. Globes and orbits appear grossly unremarkable. Intracranial: The visualized intracranial contents are grossly unremarkable in the significant limitations of this exam not tailored for evaluation of the compartment. Dentition: No dental fracture. Cervical spine: Limited evaluation without fracture, dislocation. No significant degenerative change.
Thank you so much To educate people like me who have very basic human anatomy I have question about deviated septum in the nose by birth , Is there any connection with Blood pressure I may be asking stupid question
I wish you do this with every anatomy you will save my ass I should give u half of my salary as a thank u every month since im living alone and I don’t need it other than food
